Special soil storage-enlarging capacity-enhancing fertilizer for fruit trees, and preparation method thereof

Abstract

The invention discloses a special soil storage-enlarging capacity-enhancing fertilizer for fruit trees, and a preparation method thereof. The special soil storage-enlarging capacity-enhancing fertilizer for fruit trees consists of the following raw materials and in percentage by weight: 35 to 45 percent of carbonaceous shale, 9 to 14 percent of potassium dihydrogen phosphate, 20 to 25 percent of diammonium phosphate, 10 to 15 percent of rapeseed residue, 10 to 15 percent of urea, and 1 to 2 percent of collagen. The preparation method comprises the following steps: smashing and grinding the shale, removing impurities from the powder, grading the powder, grinding the powder to be less than 1 mm after the smashing, and screening the powder with a 20-mesh sieve; performing the amination treatment on the rapeseed residue; smashing and grinding the potassium dihydrogen phosphate, the diammonium phosphate and the urea as auxiliary materials to be less than 1 mm respectively, and screening the powder with the 20-mesh sieve respectively; adding the collagen into the obtained product, and mixing and stirring the mixture; and granulating and packaging the mixture to obtain the fertilizer. 1,500 to 3,000 kg of the fertilizer used per hectare can increase the yield of fruit-tree garden crops by over 12 to 20 percent and raise water utilization ratio by over 10 to 20 percent. In arid and semi-arid areas, the fertilizer can fully utilize natural rainfall to conserve water and fertilizer and improve soil fertility, is beneficial to the yield increase of fruit trees and other crops, and canal so be used as a production fertilizer for wheat.

Description

technical field [0001] The invention relates to a preparation method of soil expansion and storage capacity-increasing fertilizer special for fruit trees, in particular to a special soil expansion and storage and capacity-increasing fertilizer for fruit trees prepared by using carbonaceous shale as the main raw material and its preparation method. Shale resources open up a new avenue. Background technique [0002] 1. Introduction to shale resources [0003] Shale, a kind of tiny particles formed by the hardening of clay materials, is easily broken and easily split into obvious rock formations. It is a kind of clay rock with complex composition. Except clay minerals (such as kaolinite, montmorillonite, etc.) , Hydromica, Baillite, etc.), it also contains many detrital minerals (such as quartz, feldspar, mica, etc.) and authigenic minerals (such as iron, aluminum, manganese oxides and hydroxides, etc.). With page or laminar bedding. It is formed by compaction, dehydration a...
